PROJECTILE.

Application led May 2, 1916.

To all whom t may camera.'

Be it known that I, ALoIs P. SwoBoDA, a citizen of the United States,residing at New York, in the county of New York, State of New York, haveinvented a new and useful Projectile; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will en` able others skilled in the art to which it appertainsto make and use the same. Y

The present invention relates to certain new and useful improvements inprojectiles, and has for its object to provide a device of thischaracter which embodies novel features of construction whereby a chargeof some highly inflammable substance can be carried by the projectileand automatically ignited and scattered upon the object struck by theprojectile.

Further objects of the invention are to provide aprojectile of thisCharacter which is comparatively simple and inexpensive in itsconstruction, which can be fired from the ordinary guns withoutnecessitating any changes therein, which may or may not carry. anexplosive charge in addition to the iniiammable substance, and which canbe handled with safety.

With these and other objects in view,the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear' as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention,

scription and accompanyingv drawings, in

which Figure 1 is a longitudinal sectional view through acartridgeloaded with aprojectile constructed in accordance with theinvenltion.

Fig. 2 is a similar view showing a modif fied form of the invention.A

Fig. 3 is a detail longitudinal sectional view through the outer end ofthe inflammable substance receiving chamber, showing the details of thevalve connecting the infiammable substance chamber and the expansionpocket.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters,

Specification of Letters Patent.

Referring to the drawings, which illustrate one possible embodiment ofthe invention, the numeral 1 designates the body of a projectile whichhas the base thereof fitted within the mouth of a cartridge shell 2,said shell containing the usual powder charge 3, and having a primer orignition cap 4 in the head thereof. The nose of-the projectile 1 istapered, as indicated at la, and has a comparatively fragile chamber 5fitted thereon, said chamber being adapted to be filled with some highlyinflammable liquid or substance, such as the gasolene 6, and having anexpansion pocket 7 in one end thereof to provide for the expansion andcontraction of the inflammable substance whichwill be incident to thechanges of temperature therein. The shell 5 is preferably cylindrical inshape, and the diameter of the shell is considerably less than that ofthe body portion 1 of the projectile or of the caliber of the gun fromwhich the projectile is to be fired. This chamber 5 will be fitted uponthe nose of the projectile in such a manner that the chamber andprojectile are coaxial and, owing to the smaller diameter of the chamber5, the walls thereof will not come into contact withthe bore of the gun,thereby preventing the chamber and the contents thereof from becomingunnecessarily heated by friction and eliminating'any possibility of thewalls of the chamber 5 being bent or ruptured by the discharge of theprojectile from the f When the projectile strikes against some object,the chamber 5 will be shattered or crushed, thereby causing the charge 6of inflammable substance to be scattered and some means, such asi: theignition cap 8, is provided for setting fire to the substance 6 at thesame time that it is scattered. The damage which will ordinarily be doneby the projectile 1 is thus augmented by the damage which may be done bythe burning of the scattered inflammable substance 6. There is thus notonly the smashing effect of the projectile to be contended with, butalso the possibility of a serious fire or coniagration being broughtabout by the burning of the inammable substance which is scattered inall directions when the walls of the chamber 5 are shattered by theimpact of the projectile against some object. In a naval engagementthere would be the possibility of setting fire to the ship of the enemy,as well as that of destroying the ship by the impact or explosion of theprojectile itself. The use of the -projectile is not by any means to belrestricted to naval warfare, however, since it can be used for thepurpose of clearing out trenches, breaking down walls, or for any kindof fighting.

The extremity of the chamber 5 is r'preferably pointed, as indicated at5a, so as to reducejthe resistance of the air to the Hight of theprojectile, and the expansion pocket 7 may be conveniently located inthe pointed end of the chamber. A transverse partition 9 separates theexpansion pocket 7 from the interior of thebody portion of the chamber5, said partition carrying a`double acting valve 10 which is constructedto admit of a back and forth movement of the inflammable liquid betweenthe chamber 5 and the expansion pocket 7'. This valve 10 may be ofanysuitable construction, and may be Y mounted in any suitable manner,although for the purpose ofillustration it is shown as arranged within atubular member 11 which extends through the partition and. interposedbetween a pair of springs 12 which bear at their outer ends againstflanges 13 projecting inwardly from the extremities of the tubularmember. The end portions of the tubular member 11, projecting uponopposite sides of the partition 9, are provided with the respectivelongitudinal'slots 14, so that when the valve 10 is moved in eitherdirection communication is established between the chamber 5 andv theexpansion pocket 7, although when the valve isin an intermediateposition the expansion pocket is cut oli' from the chamber 5. Thechamber 5 will be heated by the discharge of the projectile and therapid passage thereof through the air, and this will cause theinflammable substance to become heated and expand, although thisexpansion is taken care of by the ocket 7.

A suitable opening 15 woul be provided in the chamber 5 preferably atone side thereof, for enabling theA c amber to be readily filled withthe inflammable substance 6.' This opening could be closed in anysuitable manner, as by means of a plug 16, which is adapted to bescrewed tightly into position therein. This plug should leave theexterior of the chamber as smnoth as polble in order that there may benov :unnecessary air resistance.-

The chamber 5 may be fitted upon the nose -of the projectile 1in anysuitable manner. In the present instance the inner end of the chamber -5telescopes upon and has a threadedl engagement with a reducedcylindrical head 1b at the extremity of the nose 1'* ofthe projectile 1.The rear end of the chamber 5 may be provided with an interior ange17,and a washer orl packing ring 18 may be interposed between this iiangeand the end-of the projectile, thereby insuring This projectile isfilled with an explosive charge 19, and any conventional means, such asa cap or fuse,

may be provided for discharging the explosive charge 19 at the propertime.

The chamber 5 containing the inammable substance would be simultaneouslyshattered, and the iniammable substance ignited by the explosion of theprojectile. The chamber 5 may thus be applied to either an explosive ora non-explo'- sive projectile, or to any kind of a base for carrying thesame, and the destructiveness of any projectile to which it'may beapplied is greatly increased.

Having thus described the invention, what Lclaim as new and desire tosecure by LettersPatent, is

1. A projectile including a body havingk a contracted nose at one endthereof, a chamber having asmaller diameter than the body and fittedupon the contracted nose thereof, the chamber and body being coaxial, sothat the walls of the chamberV will not contact with the bore ofthe gun,a quantity of iniiammable material packed within the chamber andadapted' to be scattered when the chamber is broken by the impact of theprojectile with an object, and means for igniting the inflammablematerial as it is scattered. Y

2. A projectile including a body having a contracted nose at one endthereof, a chamber having a smaller diameter thanthe body and formedwith an openY end which is telescoped upon the contracted nose of thebody, the chamber and base being co-axial so that the walls of thechamber will not contact with the bore of the gun, an internal flangewithin the chamber adjacent to the open end thereof, a packing ringinterposed between the1 internal flange, and a quantity of inflammablematerial housed within the chamber and adapted to be scat-V tered whenthe chamber is shattered by impact of the projectile with an object, andmeans for ignitmg the inflammable material as it is. scattered.

3. A projectile including a body, a chamthe bodyto insure a tight joint,

no l
